Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to an Internet of Things (IoT) thread breakage alarm hook for embroidery machines. Background Technology

[0002] The thread hook is a key mechanical component of an embroidery machine, mainly composed of a housing, a drive crank, a movable hook, and a connecting rod. The housing has an internal sliding groove structure. One end of the connecting rod is hinged to the drive crank, and the other end is connected to the hook. Through the crank-connecting rod transmission, the hook is driven to reciprocate along the sliding groove, achieving the core function of hooking the bottom thread and forming the stitch.

[0003] Existing thread hooks mostly employ an open design for their grooves, allowing thread lint and fiber debris generated during embroidery to easily enter the housing through the groove gaps. As the equipment continues to operate, foreign objects may gradually accumulate within the groove, increasing the sliding resistance of the linkage or causing a deviation in its movement trajectory, making it difficult for the hook to properly retrieve the thread. Therefore, we propose an IoT-based thread hook with a breakage alarm for embroidery machines. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an IoT-based thread breakage alarm hook for embroidery machines, so as to solve the technical problem that the open design of the existing hook groove causes the intrusion of thread lint, resulting in obstructed hook movement and inaccurate hooking.

[0005] To solve the above technical problems, this utility model provides the following technical solution: an IoT-based thread breakage alarm hook for embroidery machines, including a bottom shell, a cavity inside the bottom shell, a slide rail in the middle of the cavity, a blocking mechanism arranged in the slide rail, a blocking mechanism arranged on the front surface inside the cavity, a bracket arranged on the rear surface outside the bottom shell, a linkage mechanism arranged on the bracket, a top shell arranged on the upper surface outside the bottom shell, and a photoelectric sensor arranged at one end of the top shell;

[0006] The blocking mechanism includes two inserts, a folding plate is arranged between the two inserts, and a magnetic block A is arranged on the front surface of the two inserts.

[0007] Preferably, the blocking mechanism includes a push block, the front surface of which is provided with a pull opening, and the push block is made of iron.

[0008] Preferably, magnetic blocks B are arranged at both ends of the front surface inside the cavity, and the magnetic blocks B are adsorbed and connected to the pusher block.

[0009] Preferably, a hook is arranged in the middle of the slide, a slider is arranged on the hook, a lever is arranged on the upper surface of the slider, slots A are arranged on both sides of the slider, slots B are arranged at both ends of the slide, and inserts are inserted into both slots B and slots A.

[0010] Preferably, the end of the insert has a rounded corner structure, and the inner walls at both ends of slot A and slot B have an flared structure.

[0011] Preferably, the linkage mechanism includes a shaft rotatably mounted on a bracket, a crank rotatably mounted at the head end of the shaft, a dial at one end of the crank, and a lever inside the dial.

[0012] Preferably, a sliding groove is provided in the middle of the top shell, and a lever slides in the sliding groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model designs a folded plate structure, with its two ends connected to slot A and slot B via insert blocks. When the crank pushes and pulls the slider along the slide, the folded plate folds or stretches with the slider displacement, dynamically covering the opening area of ​​the slide groove. This structure can reduce the possibility of external thread entering the slide groove through the slide groove, reduce the risk of foreign objects accumulating in the slide groove, and thus maintain the stability of the hook sliding trajectory. Through the synergistic effect of mechanical shielding and deformation compensation, it helps to improve the matching accuracy between the hook and the bottom line and enhance the reliability of continuous operation of the hook.

[0015] 2. This utility model, through the design of a plug, slot A, and slot B structure, features a rounded corner guide at the end of the plug and flared guide areas formed on the inner walls of both ends of the slot. The progressive fit between the rounded corner guide and the flared guide areas helps reduce the probability of frictional contact between the plug and the inner walls of slot A and slot B, potentially reducing structural wear during assembly. This design makes it easier for the folded plate to be inserted axially into the preset position in the slide along the cavity, and maintains insertion stability through geometric adaptation. When lint accumulates on the surface of the folded plate and needs to be cleaned, workers can directly pull it out axially without disassembling the top and bottom shells. Since the lint accumulation rate is usually higher than the wear cycle of the hook, this structural design provides convenience for periodic maintenance, balancing the shielding function with maintenance efficiency.

[0016] 3. This utility model designs a structure of magnetic block A, magnetic block B, and push block. The push block is made of iron. When it pushes the folded plate into the cavity, the magnetic block B at the front end of the cavity can form an adsorption connection with the push block, reducing the possibility of the folded plate accidentally coming out. When disassembly is required, during the process of pulling out the push block, the magnetic block A installed on the surface of the insert block and the push block generate a magnetic attraction, driving the insert block to move synchronously from slot A and slot B. This design, through the synergy of magnetic adsorption and mechanical push and pull, helps to achieve directional locking and controllable separation of the folded plate, thereby maintaining the positioning stability and maintenance convenience of the shielding component.

[0025] like Figures 1 to 6 As shown, the present invention relates to an IoT-based wire breakage alarm hook for embroidery machines, comprising a bottom shell 1, a cavity 2 inside the bottom shell 1, a slide rail 3 in the middle of the cavity 2, a blocking mechanism 4 arranged in the slide rail 3, a blocking mechanism 5 arranged on the front surface inside the cavity 2, a bracket 6 arranged on the rear surface outside the bottom shell 1, a linkage mechanism 7 arranged on the bracket 6, a top shell 8 arranged on the upper surface outside the bottom shell 1, and a photoelectric sensor 9 arranged at one end of the top shell 8.

[0026] The blocking mechanism 4 includes two insert blocks 401. A folding plate 402 is arranged between the two insert blocks 401, and a magnetic block A403 is arranged on the front surface of the two insert blocks 401. The photoelectric sensor 9 of this invention is a diffuse reflection type. The diffuse reflection photoelectric sensor 9 does not require a separate reflector or receiver. It only needs to be installed on one side near the hook 11. Its integrated design reduces the complexity of the mechanical structure and is particularly suitable for the internal layout of the embroidery machine hook with limited space. The installation of the photoelectric sensor 9 allows it to detect whether the bottom thread on the hook 11 is broken. If it is broken, it can trigger an audible and visual alarm through the chip and push the information to the workshop management system at the same time. By designing the folding plate 402 structure, its two ends are connected to the slot A14 and slot B15 through the insert block 401. When the crank 702 pushes and pulls the slider 12 to move along the slide 3, the folding plate 402 folds or stretches with the displacement of the slider 12, dynamically covering the opening area of ​​the slide groove 16. This structure can reduce the possibility of external thread entering the interior of the slide 3 through the slide groove 16, reduce the risk of foreign objects accumulating in the slide 3, and thus maintain the stability of the sliding trajectory of the hook 11. Through the synergistic effect of mechanical shielding and deformation compensation, it helps to improve the matching accuracy between the hook 11 and the bottom thread and improve the reliability of the continuous operation of the hook.

[0027] In an embodiment of this invention, the blocking mechanism 5 includes a push block 501, with a pull opening 502 arranged on the front surface of the push block 501, and the push block 501 is made of iron. The push block 501, made of iron, is more easily attracted and fixed by the magnetic blocks A403 and B10, while the pull opening 502 facilitates the application of pushing and pulling forces to the push block 501 by the operator, providing a point of application.

[0028] In this embodiment of the invention, magnetic blocks B10 are arranged at both ends of the front surface inside the cavity 2, and the magnetic blocks B10 are attracted to the push block 501. This invention, through the design of the magnetic block A403, magnetic block B10, and push block 501 structure, with the push block 501 made of iron, allows the magnetic block B10 at the front end of the cavity 2 to form an attracted connection with the push block 501 when it pushes the folded plate 402 into the cavity 2, reducing the possibility of the folded plate 402 accidentally detaching. When disassembly is required, during the pulling out of the push block 501, the magnetic block A403 mounted on the surface of the insert block 401 and the push block 501 generate a magnetic attraction, causing the insert block 401 to move synchronously from the slots A14 and B15. This design, through the synergy of magnetic attraction and mechanical pushing and pulling, helps to achieve directional locking and controllable separation of the folded plate 402, thereby maintaining the positioning stability and maintenance convenience of the shielding component.

[0029] In this embodiment of the invention, a hook 11 is arranged in the middle of the slide rail 3, a slider 12 is arranged on the hook 11, a lever 13 is arranged on the upper surface of the slider 12, slots A14 are arranged on both sides of the slider 12, and slots B15 are arranged at both ends of the slide rail 3. Insert blocks 401 are inserted into both slots B15 and A14. The hook 11 of this invention precisely hooks the bottom thread, causing it to interweave with the top thread in the fabric to form a lockstitch, ensuring the continuity and tensile strength of the embroidery stitch.

[0030] In this embodiment of the invention, the end of the insert 401 is rounded, and the inner walls of both ends of the slots A14 and B15 are flared. By designing the structures of the insert 401, slots A14 and B15, and with the insert 401 having a rounded guide portion at its end and the inner walls of both ends of the slots forming flared guide areas, the progressive fit between the rounded guide portion and the flared guide areas helps reduce the probability of frictional contact between the insert 401 and the inner walls of slots A14 and B15, potentially reducing structural wear during assembly. This design makes it easier for the folding plate 402 to be inserted axially into the preset position within the slide rail 3 along the cavity 2, and maintains insertion stability through geometric adaptation. When lint accumulates on the surface of the folding plate 402 and needs cleaning, workers can directly pull it out axially without disassembling the top shell 8 and bottom shell 1. Since the lint accumulation rate is usually higher than the wear cycle of the hook 11, this structural design provides convenience for periodic maintenance, balancing shielding function and maintenance efficiency.

[0031] In an embodiment of this invention, the linkage mechanism 7 includes a shaft 701 rotatably mounted on a bracket 6. A crank 702 is rotatably mounted at the head end of the shaft 701. A dial 703 is provided at one end of the crank 702, and a lever 13 is provided inside the dial 703. By designing the structure of the crank 702, dial 703, and lever 13, this invention allows the power transmitted from the linkage rod on the embroidery machine to be delivered to the slider 12, indirectly driving the hook 11 to move back and forth, thereby allowing the hook 11 to hook the thread back and forth.

[0032] In one embodiment of this invention, a groove 16 is provided in the middle of the top shell 8, and a lever 13 slides within the groove 16. The groove 16 of this invention allows the lever 13 to slide within it, providing a position for the power connection to slide.

[0033] Working Principle: This embodiment provides an IoT-based thread breakage alarm hook for embroidery machines. When using it, the operator must first install this device on the embroidery machine and connect it to an external power supply. During operation, the connecting rod of the embroidery machine will move the dial 703 back and forth via the crank 702. The lever 13 arranged in the dial 703 will also move accordingly. After the lever 13 moves, it will drive the slider 12 to move back and forth within the slide rail 3. The hook 11 installed on the lower surface of the slider 12 will also move back and forth, allowing one end to hook the thread. When hooking, the photoelectric sensor 9 will detect whether the bottom line is broken. When the photoelectric sensor 9 cannot detect the bottom line in the hook 11, it will send an electrical signal to the control panel, and then the control panel will trigger an audible and visual alarm. When the hook 11 hooks the bottom line, a lot of lint will be generated in the space near its operation. After the lint enters the slide 16, it will fall onto the folding plate 402. After using this utility model for a certain period of time, the operator needs to remove the folding plate 402 and clean the lint from its surface. The specific operation is that the operator inserts his / her finger into the pull opening 502 and pulls it. Pulling the pull tab 502 will dislodge the push block 501 inserted into the cavity 2. As the push block 501 dislodges, the magnetic block A403 will simultaneously pull the two insert blocks 401 out of slots A14 and B15. After being pulled out, the folding plate 402 installed between the two insert blocks 401 will also come out, allowing the worker to clean the lint from the surface of the folding plate 402. After cleaning, the worker pulls the folding plate 402, positioning the two insert blocks 401 at both ends inside the cavity 2. Then, the worker removes the push block 501 and inserts it into the cavity 2. Inside, push the push block 501 and push the two insert blocks 401 into the slots A14 and B15, thereby placing the folding plate 402 on the slide 3 and below the slide groove 16 to continue blocking the lint. After the push block 501 is pushed into the cavity 2, it will be attracted and fixed by the magnetic block B10 installed in the cavity 2. Of course, when the hook 11 is damaged, the operator can unscrew the screws to separate the bottom shell 1 and the top shell 8. After separation, the operator can take out the hook 11 from the slide 3 for replacement so that the utility model can be used normally in the future.

Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
